; Exercise 1.4
; Observe that our model of evaluation allows for combinations 
; whose operators are compound expressions. Use this observation to describe
; the behavior of the following procedure:

(define (a-plus-abs-b a b)
  ((if (> b 0) + -) a b))

; If b is bigger than 0, sums a to b, and subtracts it otherwise
; In other words, it sums a to (abs b), as the name implies
